Option cleanups: --get is not upload --form* are post - added several options into ldap, smtp, imap and pop3 - shortened the category descriptions in the list category curl fixes: --create-dirs removed from 'curl' --ftp-create-dirs removed from 'curl' --netrc moved to 'auth' from 'curl' --netrc-file moved to 'auth' from 'curl' --netrc-optional moved to 'auth' from 'curl' --no-buffer moved to 'output' from 'curl' --no-clobber removed from 'curl' --output removed from 'curl' --output-dir removed from 'curl' --remove-on-error removed from 'curl' Add a "global" category: - Made all "global" options set this category Add a "deprecated" category: - Moved the deprecated options to it (maybe they should not be in any category long term) Add a 'timeout' category - Put a number of appropriate options in it Add an 'ldap' category - Put the LDAP related option in there Remove categories "ECH" and "ipfs" - They should not be categories. Had only one single option each. Remove category "misc" - It should not be a category as it is impossible to know when to browse it. --use-ascii moved to ftp and output --xattr moved to output --service-name moved to auth Managen fixes: - errors if an option is given a category name that is not already setup for in code - verifies that options set `scope: global` also is put in category `global´ Closes #14101

# `--keepalive-time`
|
|
|
|
Set the time a connection needs to remain idle before sending keepalive probes
|
|
and the time between individual keepalive probes. It is currently effective on
|
|
operating systems offering the `TCP_KEEPIDLE` and `TCP_KEEPINTVL` socket
|
|
options (meaning Linux, *BSD/macOS, Windows, Solaris, and recent AIX, HP-UX and more).
|
|
Keepalive is used by the TCP stack to detect broken networks on idle connections.
|
|
The number of missed keepalive probes before declaring the connection down is OS
|
|
dependent and is commonly 8 (*BSD/macOS/AIX), 9 (Linux/AIX) or 5/10 (Windows), and
|
|
this number can be changed by specifying the curl option `keepalive-cnt`.
|
|
Note that this option has no effect if --no-keepalive is used.
|
|
|
|
If unspecified, the option defaults to 60 seconds.
